Step 6: Risk Mitigation Strategies

1. Start Small: Begin with trial order (100-300 units) to validate product and supplier before scaling ^[9]

2. Diversify Suppliers: Avoid single-source dependency; qualify 2-3 backup suppliers

3. Quality Assurance: Implement incoming quality inspection, consider third-party inspection services

4. Contract Protection: Use detailed contracts with clear specifications, warranty terms, and dispute resolution

5. Intellectual Property: File patents/trademarks in target markets, use NDAs with suppliers

6. Regulatory Compliance: Budget adequate time and resources for certifications; don't launch before approval

7. Customer Feedback Loop: Establish mechanisms for collecting and acting on user feedback post-launch
